Shadows change during the day because of the position of the sun. The sun is constantly moving across the sky, and as it does, the shadows cast by objects also move. This is why we see different shapes and sizes of shadows at different times of the day.
During the day, the sun moves from east to west. This means that the shadows cast by objects will also move from east to west. As the sun moves, the shadows will get longer or shorter, depending on the position of the object.
The size of the shadow will also change during the day. This is because the sun is not always in the same position in the sky. When the sun is high in the sky, the shadows will be smaller. When the sun is low in the sky, the shadows will be larger.
The direction of the shadow will also change during the day. This is because the sun moves around the Earth. As the sun moves, the shadows will change direction.
All of these changes can be seen throughout the day. Shadows will constantly change shape, size, and direction.
